From 1765c8bcecfb357c8711199c19ecbeb06421b198 Mon Sep 17 00:00:00 2001 From: Brian O'Kelley Date: Mon, 10 Nov 2025 09:28:26 -0500 Subject: [PATCH 1/4] feat: add ergonomic .simple accessor to all ADCPClient instances MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The .simple property provides a simplified API with kwargs-based methods that return unwrapped response data and raise exceptions on errors. This makes the SDK more ergonomic for examples, documentation, and quick testing while maintaining backward compatibility with the standard API. Changes: - Add SimpleAPI class (src/adcp/simple.py) that wraps all client methods - Add .simple accessor to ADCPClient initialized in __init__ - Update README with new quick start examples using .simple - Add comprehensive example demonstrating both API styles - Add tests verifying .simple works on all client instances The standard API remains unchanged for production use cases that need full control over error handling and TaskResult metadata. 🤖 Generated with Claude Code Co-Authored-By: Claude --- README.md | 62 ++++++-- examples/simple_api_demo.py | 146 +++++++++++++++++ src/adcp/client.py | 5 + src/adcp/simple.py | 299 +++++++++++++++++++++++++++++++++++ src/adcp/testing/__init__.py | 15 ++ tests/test_simple_api.py | 158 ++++++++++++++++++ 6 files changed, 668 insertions(+), 17 deletions(-) create mode 100644 examples/simple_api_demo.py create mode 100644 src/adcp/simple.py create mode 100644 tests/test_simple_api.py diff --git a/README.md b/README.md index b56b0d4..d27b993 100644 --- a/README.md +++ b/README.md @@ -26,36 +26,64 @@ pip install adcp ## Quick Start: Test Helpers -The fastest way to get started is using the pre-configured test agents: +The fastest way to get started is using pre-configured test agents with the **`.simple` API**: ```python from adcp.testing import test_agent -from adcp.types.generated import GetProductsRequest -# Zero configuration - just import and use! -result = await test_agent.get_products( - GetProductsRequest( - brief="Coffee subscription service", - promoted_offering="Premium coffee deliveries" - ) +# Zero configuration - just import and call with kwargs! +products = await test_agent.simple.get_products( + brief='Coffee subscription service for busy professionals' ) -if result.success: - print(f"Found {len(result.data.products)} products") +print(f"Found {len(products.products)} products") +``` + +### Simple vs. Standard API + +**Every ADCPClient** includes both API styles via the `.simple` accessor: + +**Simple API** (`client.simple.*`) - Recommended for examples/prototyping: +```python +from adcp.testing import test_agent + +# Kwargs and direct return - raises on error +products = await test_agent.simple.get_products(brief='Coffee brands') +print(products.products[0].name) +``` + +**Standard API** (`client.*`) - Recommended for production: +```python +from adcp.testing import test_agent +from adcp.types.generated import GetProductsRequest + +# Explicit request objects and TaskResult wrapper +request = GetProductsRequest(brief='Coffee brands') +result = await test_agent.get_products(request) + +if result.success and result.data: + print(result.data.products[0].name) +else: + print(f"Error: {result.error}") ``` -Test helpers include: -- **`test_agent`**: Pre-configured MCP test agent with authentication -- **`test_agent_a2a`**: Pre-configured A2A test agent with authentication -- **`test_agent_no_auth`**: Pre-configured MCP test agent WITHOUT authentication -- **`test_agent_a2a_no_auth`**: Pre-configured A2A test agent WITHOUT authentication +**When to use which:** +- **Simple API** (`.simple`): Quick testing, documentation, examples, notebooks +- **Standard API**: Production code, complex error handling, webhook workflows + +### Available Test Helpers + +Pre-configured agents (all include `.simple` accessor): +- **`test_agent`**: MCP test agent with authentication +- **`test_agent_a2a`**: A2A test agent with authentication +- **`test_agent_no_auth`**: MCP test agent without authentication +- **`test_agent_a2a_no_auth`**: A2A test agent without authentication - **`creative_agent`**: Reference creative agent for preview functionality - **`test_agent_client`**: Multi-agent client with both protocols -- **`create_test_agent()`**: Factory for custom test configurations > **Note**: Test agents are rate-limited and for testing/examples only.
